can of whoopass

"I'm gonna open up a can of whoop-ass on ya", a common threat used in the late 1990's to imply that if an individual did something, or did not stop doing something you were going to beat them severly. The severity of the beating could be altered by changing the "container" which was to be full of "whoop-ass"

Slang term for a particularly savage beating, whether actually delivered with one's fists or by some other method that reduces the offending party to a state of defeated submissiveness. As in, "I'm gonna have to open up a can of whoopass on you, boy." Also spelled "Whup ass".
